2 box plots. The number line goes from 175 to 450. For resort A, the whiskers range from 175 to 375, and the box ranges from 250 to 300. A line divides the box at 375. For Resort B, the whiskers range from 200 to 400, and the box ranges from 300 to 375. A line divides the box at 325. Which statement is true of the snowfall data in the box plots? Check all that apply. The median snowfall for Resort A is greater than the median for Resort B. The median snowfall for Resort B is greater than the median for Resort A. The interquartile range has higher values for Resort A than for Resort B. The data have more variation for Resort A than for Resort B. Resort B has more snowfall overall than Resort A does.

Mathematics

has PDF

$f_X(x)=\begin{cases}\frac1{10}&\text{for }0\le x\le10\\0&\text{otherwise}\end{cases}$

and thus CDF

$F_X(x)=\begin{cases}0&\text{for }x10\end{cases}$

Because is continuous, we have

$P(X8)=1-P(1\le X\le8)=1-(P(X\le8)-P(X\le1))$

$P(X8)=1-P(X\le 8)+P(X\le1)$

P(X8)=1-F_X(8)+F_X(1)

$P(X8)=1-\dfrac8{10}+\dfrac1{10}=\boxed{\dfrac3{10}}$
